Aiming at the problem that the cement stabilized gravel base layer commonly used in primary roads and motorways is prone to shrinkage cracks,a kind of crack-resistant cement stabilized gravel base layer material with intermittent grading is determined according to the Bailey method and the main aggregate void filling method,and the proportion design of the crack-resistant cement stabilized gravel base layer mate-rial is carried out,and a series of synthetic grading and strength indexes are obtained by the tests,which are verified in the experimental section.
